				        	Objective To study the effect of ganoderma lucidum polysaccharides combined with metformin on oxidative stress of type 2 diabetic rats. Methods SD rats were fed with high fat diet for 4 weeks and injected with streptozotocin (30 mg·kg-1 ) to produce type 2 diabetic model. The diabetic rats were randomly divided into diabetes model group, ganoderma lucidum polysaccharides group (600 mg·kg-1 ), metformin group (600 mg·kg-1 ), combination group (ganoderma lucidum polysaccharides 300 mg·kg-1+ metformin 300 mg·kg-1 ), After 12 weeks of treatment, the level of fasting blood glucose was determined, and the activity of superoxide dismutase ( SOD), malondialdehyde ( MDA), catalase ( CAT), glutathione peroxidase (GSH-Px), total cholesterol (TC) and triglyceride (TG) were detected. Results The levels of fasting blood glucose in the treatment groups were significantly lower than that in the diabetes model group (P<0. 01). Furthermore, fasting blood glucose in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group (P<0. 01). Compared with diabetes model group, serum TC and TG in the treatment groups were significantly lower (P<0. 05, P<0. 01). Serum TC and TG were significantly lower in the combination group than in ganoderma lucidum polysaccharides group and metformin group (P<0. 05, P<0. 01). Compared with diabetes model group, serum SOD levels in the treatment groups were significantly higher (P<0. 01). Compared with ganoderma lucidum polysaccharides group and metformin group, serum SOD levels in the combination group was significantly higher (P<0. 05). Compared with diabetes group, serum MDA levels in the treatment groups were significantly lower (P<0. 01). Serum MDA in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group ( P<0. 05). Compared with diabetes model group, serum CAT and GSH-Px in the treatment groups were significantly higher (P<0. 05, P<0. 01). Serum CAT and GSH-Px in the combination group were significantly higher than those in ganoderma lucidum polysaccharides group and metformin group (P<0. 05). Conclusion Ganoderma lucidum polysaccharides combined with metformin could effectively inhibit oxidantion stress in type 2 diabetic rats. The effect was better than ganoderma lucidum polysaccharides or metformin used alone. The possible mechanism may be related to increased activity of SOD, CAT, GSH-Px in vivo and regulation of dyslipidemia.
